Cell Transport Review

​Cell Transport

​Quiz #5 is TOMORROW (Tuesday)

​

There are two big key ideas to make sure you know and understand.

​

​Quiz #5 will have 10 questions...

• ​7 on cell transport

• ​2 on states of matter

• ​1 on Law of Conservation of Mass

​Key Idea #1

• The cell membrane (semi-permeable) controls what enters and leaves a cell.

​

• It does this to maintain ‘equilibrium’ or homeostasis, a stable internal environment despite external environment, which allow smaller molecules like water to enter, but larger molecules cannot.

​Key Idea #2

• ​Passive transport like diffusion and osmosis, requires no energy on the cell’s part because it is moving from HIGH to LOW concentration levels.

​

• Active transport requires energy because the molecules are larger and move from LOW to HIGH concentrations.
